systems promote water
conservation. If you have a sprinkler system, annual
maintenance, proper controller programming and appropriate schedules
are the best ways to improve the health of your landscape and save you
The keys to efficient watering are to properly
adjust controller schedules monthly during the active season, reduce
watering of established shrubs and trees, and program your controller
to run the sprinklers before 9:00 AM to reduce evaporation.
Many modern controllers allow you to adjust your watering schedule
using a built-in feature such as “seasonal adjust”. This feature allows
change the length of the water cycle for all zones simultaneously.
sprinkler heads in each zone: Pop-ups and rotors
have different distribution rates. Unmatched heads within the same area
results in over-irrigation of some parts of your garden in order to get
adequate amounts to other areas. Solution: NPL can update
your system for uniform coverage, improved plant health and prevent
unnecessary water loss.
low-head drainage: After the zone has
completed its cycle, water should not continuously leak from the head.
Sprinklers with built-in check-valves prevent the water from draining
from the pipe on slopes. Solution: NPL can upgrade problematic
sprinklers to prevent water waste that will provide a cost savings to
water run-off: If run-off occurs
shortly after watering begins, soil compaction, quality, or grade may
be the problem. Solution: NPL can aerate your lawn or set multiple
start times for each
zone to allow the water to soak in after each watering cycle.
misting and/or unnecessary
over-spray: This occurs when you have excessive system pressure.
Solution: NPL can install a pressure-regulating valve to reduce system
pressure. This will result in improved plant health and
permit water conservation.
